Following previous work [1]}, [2]}, [3]}, [4]}, [5]}, we used CD and F-Score to evaluate the reconstruction accuracy. We denote the reconstructed and ground-truth mesh by \(\mathcal {S}_\text{REC}\)  and \(\mathcal {S}_\text{GT}\) , on which we randomly sample a set of \(10^5\)  points, denoted as \(\mathcal {P}_\text{REC}\)  and \(\mathcal {P}_\text{GT}\)  and the CD of these two meshes is that of the two point sets, i.e.,
\(\texttt {CD}(\mathcal {S}_\text{REC},\mathcal {S}_\text{GT})=\texttt {CD}(\mathcal {P}_\text{REC},\mathcal {P}_\text{GT}).\)
